SPECIFICATION forming part of Letters Patent No. 465,561, dated December 22, 1891.

Application filed March 2, 1891.A Serial No. 383,416. (No model.)

To all whom, it 17mg/ concern:

Be it known that I, OYRUS S. HOOD, a citizen of the United States, residing at Corning, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. j

Prior to my invention door-registers as ordinarily constructed have been provided with a rectangular surface plate consisting of central fret-work or open-work and an adjacent border surrounding the open-work and connected thereto at short intervals. The necessary consequence of this multiplicity of connect-ing points between the two has been -that the heat imparted to the fret-work (which against.

One of the objects of my invention is to practically eliminate this source of danger by Vlessening the number of connecting-points between the fret-work and border, while at lthe same time providing that the fewer connections employed shall be of such character as to make the union between the two none the less stable, strong, and durable. To this end in casting the surface plate I provide that the fret-work shall only be connected with the border at or near the inner angles or corners of the latter, but by means of iianges, which, extending from a downwardly-projecting rim of the border, connect with the lower surface of the fret-work, terminating at a short distance from the angle in a gradual taper, as will more fully appear from the fuller detailed description hereinafter given.

In the ordinary construction of floor-registers another disadvantage (which my invention is designed to remove) is that the floor-carpet cannot be taken up withoutlifting out or removing in addition to the surface plate the tin box-casing beneath it which is secured to the under side of the border, and with which the hot-air pipe from the furnace connects. 5 5

hastened by the exhaust action of the hot-air f current. This undesirable condition of affairs I completely obviate by a construction permitting the removal of the surface plate without disturbing in anyway the casing beneath it or the joint between such casing and the hot-air pipe. As incidental to this con` struction' I impart to the interior of the casing a'form or configuration presenting practically no lodging-place for the accumulating of thick deposits of dusta fault present in the usual rectangular boX-casings. I take additional precautions, moreover, against danger from conflagration by providing the casing with stud projections extending from its edge and projecting into the ooring, said stud projections serving as the only means for supporting the casing, whereby a free space is left almost entirely around the upper edge of the casing between it and the flooring, correspondingly diminishingthe conduction of heat from the one to the other. To reduce the danger from re to a still greater degree, I interpose between the carpet and the under face of the border portion of the surface plate a strip of asbestus paper or its equivalent, and this strip I continue as a packing for the flange and recess joint between the casing and the down wardly-proj ecting rim, heretofore referred to, of the borderplate. The strip thereby subserves the double purpose of an additional safeguard against lire and to effectually prevent the drawing in of cellar-gases at the joint in question.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a central cross-section of a floor-register and its appurtenances embodying my invention. Fig. 2 represents, on a larger scale, abottom view of a corner of the surface plate of` the register, said corner being represented as slightly tilted backward in order to more fully show its construction. Fig. 3 represents a top IOO and having the usual dampers e.

plan view of the register, and Fig. at repre sents a top plan view of the casing and illus trates the manner of supporting it from the iiooring.

Similar letters of referenceindicate similar parts throughout the several views.

Referring to the drawings, A indicates a ioor, and a the carpet thereof, said iioor being cut away, as shown, to accommodate the Hoor-register. The floor-register consists, primarily, of two partswan upper surface plate and a lower casing B, said casing being connected to the hot-air pipe or furnace-pipe C It will be noted that the casing B is of less width and length than the iioor-openin g, from which it is separated by an intervening .space spanned only by the projecting studs or lugs b, which project into the flooring, thereby sufficiently supporting the casing, but leaving its main body portion out of actual contact with the wood. The casing Ktapers gradually 'toward the :oblong elliptical -opening through which the advantage of leaving no corners yor angles to serve as lodgin g-places for the accumulation bf dust deposits, `and also permitting an ordinary round pipe of proper dimensions -to be readily tte'd within said opening so as 'to completely till the same.

The yupper edge of the casing Bis provided with a groove n, as shown, for the reception of the-downwardly-proj ecting rim-flan ge d ot' the surface plate, land in order to insurea tight tit between the said Ygroove and rim a packing m is interposed between the two. y Said packing is pret'erablyot' asbestus cloth or like noniniamimable material, which is a poor couductor of heat .and yet sufiiciently .dense'to prevent the passage of the cellar-gases through the joint. It is continued, as shown, so'asto extend between the carpet aand the border f lof the :surface plate, thereby largely protecting the carpet from the heat of the said border.

To prevent the border itself from being unduly heated is, as I have heretofore explained, one ofthe main objects of my invention,and `to this end the connection between said borde'r and the central fret-work r is made by means of deep iianges sat-or near the cornerangles, the fret-work being otherwise Idisconnected from the border. This larrangement 'reduces the conduction of heat from the fretwork to the border to a minimum, while the flanges ys, by reason of 'their depth and because of the fact'that they extend for a short distance beneath the fret-work, as shown, furnish a reliable supporting connection for the latter.

The preferable location for the supportingyflanges s is at or substantially at the cornerangles. I-t is obvious, however, that instead of vbeing located kat the corners they may be placed ata greater or less distance therefrom tion.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

l. In a register, the combination, with the central fret-work, of a surrounding border, a downwardly-projecting rim from said border, and supporting vflanges extending downwardly from the fret-work and connecting it to the rim, the fret-work being otherwise separated from the border by an intervening free space, substantially as described.
